Question

我有150名员工和他们的工资数据我需要交换employee_id 120和121的工资假设employee_id 120的工资是8000 employee_id 121的工资是8200 所以我需要交换id＆＃39的

的工资

Answer 1

如果您已经知道两位员工的最终工资，那么我认为您可以在一个UPDATE查询中对这些值进行硬编码：

UPDATE yourTable
SET
    salary = CASE WHEN employee_id = 120 THEN 8000 ELSE 8200 END
WHERE
    employee_id IN (120, 121)

如果我读得正确的话，假设您希望员工120的薪水为8000而121的薪水为8200。

Answer 2

示例数据： -

ID Sal

120 8000

121 2000

添加120和121的工资（比如8000和2000）并将其更新为120的新工资.120的工资为10000

UPDATE yourtable
   SET sal=(SELECT sum(sal) from yourtable where id in (120,121))
 WHERE ID = 120

ID Sal

120 10000

121 2000

现在将薪水121更新为薪水121和120

之间的差额

UPDATE yourtable y
   SET sal=(SELECT sal-y.sal from yourtable where id =120)
 WHERE ID = 121

ID Sal

120 10000

121 8000

现在将薪水120更新为薪水121和120

之间的差额

UPDATE yourtable y
   SET sal=(SELECT y.sal-sal from yourtable where id =121)
 WHERE ID = 120

ID Sal

120 2000

121 8000

Answer 3

有了这两个id，这个简单的UPDATE可以做到：

update tabename t1
set sal = (select sal from tablename t2 where t2.id = 241 - t1.id)
where t1.id in (120, 121)

对于id 120，从id 241 - 120 =＆gt;中选择薪水。 id 121的薪水。

对于id 121，从id 241 - 121 =＆gt;中选择薪水。 id 120的薪水。

Answer 4

你也可以这样试试，如果您再次遇到此类问题，则可以在需要更改emp_id的情况下使用它。

     declare @str120sal varchar(25);
     declare @str121sal varchar(25);
     select @str120sal=salary from  EmpTbl where employee_id=120;
     select @str121sal=salary from  EmpTbl where employee_id=121;
     update EmpTbl set salary=@str120sal where employee_id=121;
     update EmpTbl set salary=@str121sal where employee_id=120;

Answer 5

另一种解决方案。

;WITH CTE AS (
    SELECT *, 
        RN_ASC = ROW_NUMBER() OVER(ORDER BY employee_id),
        RN_DSC = ROW_NUMBER() OVER(ORDER BY employee_id DESC)
     FROM employees WHERE employee_id IN (120,121)
 )
 UPDATE T1
 SET salary = T2.salary
 FROM CTE T1 INNER JOIN CTE T2 ON T1.RN_ASC = T2.RN_DSC

Answer 6

这是确切的答案

update e1  set e1.Salary = (select e2.salary from [EmployeeSalSwap] e2 where e2.id = (155- e1.Id) ) from TempOps.dbo.EmployeeSalSwap as e1    where Id in (75,80)

Answer 7

CREATE TABLE  salary (
    emp_id int(11) NOT NULL,
    salary float NOT NULL,
    dept int(11) NOT NULL,
    PRIMARY KEY (emp_id)
) ENGINE=InnoDB DEFAULT CHARSET=latin1

INSERT INTO salary VALUES(100, 10000, 5),(101, 20000, 4),(103, 15000, 6),(104, 12000, 2)

UPDATE salary s1,salary s2 SET s1.salary = s2.salary, s2.salary = s1.salary WHERE s1.emp_id=100 AND s2.emp_id = 104

我需要在sql中交换2名员工的工资
